I'd certainly love to buy it as Duotron was the pin that got my lifelong love of pinball started! It was the only pinball machine around to play in my home town and all us teenagers played it (almost) to death in '78 and '79 and I certainly fed plenty of coin into it.
I've never seen another one since, but I'll buy one some day....
and Wayner, I'm talking about NWC in W.A. so I know what you mean about the prices over here.
